Abstract: An apparatus and methods are provided for an air cleaner to be mounted onto an air inlet of an internal combustion engine. The air cleaner comprises an air filter that includes a filter medium disposed between a curved base and a cover. The curved base provides an interface between the air filter and the air inlet, and comprises a shape that provides clearance between the curved base and an electric choke installed onto a carburetor comprising the air inlet. The cover secures the air filter and the curved base to the air inlet such that an airstream is drawn through the filter medium and is conducted into the air inlet. A raised portion of the cover is configured to cooperate with the curved base to ensure a desired volume of the airstream is available to the air inlet at substantially all engine speeds.

Abstract: A sound attenuating engine exhaust system and methods are provided for directing exhaust gases away from an internal combustion engine of a vehicle and attenuating undesirable exhaust sounds during engine operation. The sound attenuating engine exhaust system comprises an exhaust inlet configured to receive exhaust gases from the internal combustion engine. A first resonator coupled with the exhaust inlet is configured to dampen at least one frequency of exhaust sound waves by way of destructive wave interference. The first resonator includes an exhaust outlet for directing the exhaust gases out of the first resonator. A second resonator is coupled with the first resonator and configured to dampen one or more frequencies of exhaust sound waves by way of a combination of destructive wave interference and Helmholtz resonance. Hangers facilitate attaching the sound attenuating engine exhaust system to an undercarriage of the vehicle.

Abstract: An apparatus and method are provided for a breather vent configured to be mounted onto a crankcase breather inlet of an internal combustion engine, such that particulate matter and contaminates are removed from an airstream entering into an interior of the crankcase. The breather vent comprises a base including a fitting receiver configured to retain a breather end of an adaptive fitting. An inlet end of the adaptive fitting is configured to be coupled with the crankcase breather inlet of the engine. A filter medium is fastened to the base and configured to remove the particulate matter and contaminates from the incoming airstream. The filter medium circumferentially surrounds the interior cavity and forms an exterior perimeter of a portion of the cavity. A cap is affixed to the filter medium, such that the filter medium is retained between the base and the cap.
